Black rhino charges jeep at Kruger National Park: Watch the clip

For two workers at Kruger National Park in South Africa, trying to see some cheetahs on their lunch break turned into much more than they bargained for.

Farm manager Andrew Taylor, 28, and assistant lodge manager Sam Vorster, 27, said they heard from park visitors about a cheetah sighting, so they decided to search for the big cats on their free time. This would prove to be a near costly choice — when what Taylor thought was just a large rock turned out to be a black rhinoceros.

Once they realized they had a rare chance to see the critically endangered species, the two men parked their jeep to start recording the beautiful creature.
